Ref just followed the rules, if you want to blame some1, blame RvP for his stupid decision. He knows that he can received a yellow card for that, the excuse of "i din't hear it" is pathetic. About the penalty, Pedro clearly tackled by Koscielny. Don't even see a blink of doubt there.
Btw, if some1 wants to whine about the referee, do it over that penalty over Messi that wasn't even a foul.
Ref did what he was supposed to do, don't cry about it. Cry over your unbalanced team and Wenger that clearly had the idea of emulating Mourinhos Inter but he forgot that he doesn't have the same luck that Mou had last year neither the same disciplined players.
